AIR COOLING, CLEANSING, AND VENTILATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 586,365, dated July 13,1897.

Application filed February 17, 1897. Serial No. 623,819. (No model.)

To aZZ whom, it may concern.-

Be it known that I, JOSEPH MCCREERY, a citizen of the United States,residing at T0- ledo, in the county of Lucas and State of Ohio, haveinvented certain new and useful Improvements in Air Cooling andCleansing Devices; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to an improvement in an air cooling and cleansingdevice to be used in a system of ventilation; and the drawings show onlyenough of the ventilating system to illustrate the invention, the otherparts of the system being such as would be ordinarily employed. I

The invention consists of a case or receptacle provided with the detailsof construction hereinafter set forth.

In the annexed drawings, Figure 1 represents a perspective View of thedevice, the case being broken away to show the interior construction.Fig. 2 represents a longitudinal vertical section. Fig. 3 represents atransverse vertical section on the line X X, Fig. 2, looking in thedirection of the arrow.

In the drawings the letter A represents a case of any suitable size andconstruction. (Shown in the drawings as rectangular.) This case isprovided at one end with an air-inlet a and at the other end with'anair-outlet a, the inlet being above the plane of the outlet. Attached tothe end of the case, a under the air-inlet a, is an inclined shelf orbaflie-plate B. This baffle-plate is also attached at its side to thesides of the case, but its inner end Z) stops short of the end of thecase opposite to the end a Secured to this opposite end a is the edge ofanother inclined shelf or baffle-plate O, the sides of which are securedto the sides of the case A. The other end 0 of the baflie-plate 0 stopsshort of the end a but passes beyond the end 19 of the baffle-plate B,so that these baffle-plates overlap each other, as shown in thedrawings. The end b of the baffle-plate B is in the same plane as theupper surface of the baffle-plate, but the end 0 of the bafiie-plate Ois turned up and back upon itself, forming a trough at that end of thebaffleplate C. Just within this end 0 the baffle-plate O is providedwith a down-pipe c, which opens from the top of the baiiie-plate downbelow. Just below the inner end of the baffie-plate O a trough D'extendsfrom side to side of the case A and is provided with a down-pipe (Z,which opens near the bottom of the case A.

At the secured end 0 of the baffi e plate C is placed an ice-receptaclejust above the baffle-plate. In the present instance this is made bysecuring a number of bars 6, extending in the nature of a rack from thebaffle-plate C to the top of the case A, there being a space leftbetween these bars 6 and the end Z) of the baffie-plate B. The case A isprovided with an overflow-pipe a The outlet at is connected with anyordinary blower F, having an outlet f. To the air-inlet Ct at or nearthe top of the case A is secured the pipe G, leading from awater-supply.

In use this apparatus is placed in connection with a system ofventilation, the air-inlet abeing connected with an air-shaft extendingto the source of air-supply and the outlet f being connected to the pipethrough which the air is to be forced to the apartment to be ventilated.If desired, ice is to be placed in the ice-receptacle, as shownin Fig.2.As soon as the fan F is put in operation air is drawn through the inletat, around the baffle-plates B and C, out of the outlet a, and outthrough the outlet F. At the same time water is admitted through thepipe G and commingles with the air as the latter is drawn through theinlet C6. The water and air thus coinmingle, pass down the baffle-plateB, around the edge Z7, and against the baflie-plate C. The air becomesthoroughly saturated with moisture, which not only cools it, but alsocleanses it. The surplus Water, carrying with it the matter taken fromthe air, falls upon the baflie-plate C and runs down into the trough atthe end 0, part running through the pipe 0 to the bottom of the case,the main portion running into the trough D, thence through the pipe d'tothe bottom of the case and through the overflow a The air, thoroughlycleansed and cooled so far as the temperature of the water may affectit, and deprived of surplus moisture at the trough D, where theseparation of air and IOC water occurs, passes through the outlet at. Ifdesired to cool-the air to a lower degree than that which may beobtained by the temperature of the water alone, the ice-receptacle isused. The air and water, passing down the baffle-plate B, strike againstthe ice in the ice-receptacle and both air and water are reduced intemperature, the air becoming cooled by its contact with the ice andkept cool by its being commingled with the water, also cooled by contactwith the ice.

While only two baffle-plates are shown in the drawings, for the sake ofsimplicity, it is obvious that a case may be made with any number thatis desired, the number depending somewhat upon the place and climate inwhich the device is to be used; also, an icereceptacle may be placed atthe end of each baffle-plate except the last.

, Having described my invention, what I claim, and desire to secure byLetters Patent, is

1. An air-cleansing device provided with a number of baffle-plates, thelast of which has a trough at one end, and an outlet-pipe at suchtrough, as set forth.

2. An air-cleansing device provided with a number of bafile-plates, thelast of which has a trough at one end, an outletpipe at such end, and atrough below such end, as set forth.

3. An air-cleansing device provided with a number of baffie-plates, thelast of which has a trough at one end, an outlet-pipe at such end; and atrough below the lower end of said baffle-plate, the latter trough alsohaving an outlet-pipe, as set forth.

4. An air-cleansing device provided with baffle-plates, and anice-receptacle placed opposite the end of one of the bathe-plates, therebeing a space between such end and the icereceptacle, as set forth.

5. An air-cleansing device provided with baffle-plates, and anice-receptacle placed opposite the end of one ofthe baffle-plates, therebeing a space between such end and the icereceptacle, and there being noice-receptacle between the end of the last bathe-plate and the side ofthe air-cleansing device, as set forth.

6. An air-cleansing and cooling device provided with baffle-plates, andan ice-receptacle opposite to the end of'one of the first baffle-plates,as set forth.

7. The air-cleansing and cooling device, A, having the baffie-plates, Band O, overlapping each other, the end, c, of the baffle-plate, 0, beingturned back to form a trough, and having the outlet-pipe, c; the trough,D, across the case and under the lower end of the baffle-plate andhaving the down-pipe, (Z, as set forth.

8. The air-cleansing and cooling device, A, having the baffle-plate, B,secured at one end of the case, but stopping short of the other end, andthe ice-receptacle placed between the bathe-plate, B, and the end of thecase, as set forth.

9. The case, A, provided with the battleplates, B and O, the latterhaving a trough at one end, and the air-inlet, a, and air-outlet, a,=with a water-supply pipe, .G, connected to the air-inlet, a, as setforth.

In testimony whereof I aflix my signature in presence of two witnesses.

V JOSEPH MOCREERY.
